Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel nail beauty product. More specifically, the present invention relates to a nail polish containing organically modified montmorillonite, silica, an anionic surfactant, and a non-aromatic solvent.

That is, the present invention relates to a nail beauty product that is safe for the human body, does not cause precipitation of pigments or pearlescent agents, has excellent stability over time, and has good coating film properties and usability.

[Prior Art] Conventionally, organically modified montmorillonite has been blended into nail polishes to prevent pigments and pearlescent agents from settling by utilizing its good thixotropic properties derived from clay minerals. In this case, toluene as a solvent,
Aromatic hydrocarbon solvents such as xylene have been used. Aromatic hydrocarbon solvents such as toluene swell the clay and form the best gels, and nail polishes containing such gels exhibit relatively good dispersion stability and settle and separate over time. Toluene and the like were considered indispensable as solvents for this type of nail polish because they do not cause any pollution.

There is also an example (Japanese Unexamined Patent Publication No. 174003/1983) in which hydrophobic silica was added to further improve dispersion stability and stability over time.
These use gel compositions that require toluene, so
Naturally, nail polishes also contain toluene. On the other hand, as a gel composition for nail polish that does not contain aromatic hydrocarbon solvents such as toluene and xylene, there is an example (Japanese Patent Publication No. 61-001044) in which a hydroxyl group-containing polar substance and a phenyl group-containing organic silicone compound are specifically blended. The technology for safe nail polish has been established.

[Problem to be solved by the invention] Aromatic hydrocarbon solvents such as toluene and xylene have safety issues for the human body, and there is a concern that frequent use of nail polish may cause damage or pain to the nails. It is known that there is In addition, Japanese Patent Publication No. 61-001044, which does not contain toluene, xylene, etc., is safe for the human body and has thixotropic properties, and has somewhat good dispersion stability and stability over time, but in terms of stability it is even worse. In view of this situation, the present inventors, who had room for improvement, developed a nail polish that was safe for the human body, had excellent dispersion stability, and stability over time, as well as excellent coating properties and usability. After careful consideration,
It has been found that a nail polish containing organically modified montmorillonite, silica and a non-aromatic solvent can solve these problems (Japanese Patent Application No. 63-67066). however,
This product was not yet fully satisfactory in terms of long-term stability. The inventors of the present invention have conducted repeated studies to develop a nail polish that can also satisfy long-term stability, and as a result, they have developed a nail polish that essentially contains organically modified montmorillonite, silica, an anionic surfactant, and a non-aromatic solvent. We have found a solution to all these problems and have completed the present invention.

[Means for Solving the Problems] That is, the present invention provides a nail polish that essentially contains organically modified montmorillonite, silica, an anionic surfactant, and a non-aromatic solvent.

Aromatic hydrocarbon solvents such as toluene and xylene, phenyl group-containing organic silicones, and the like that have been used so far are substances that swell the clay and impart thixotropic properties. However, the present invention does not use toluene, xylene, etc. at all, uses a non-aromatic solvent that is safe for the human body, provides excellent thixotropy through the interaction of organically modified montmorillonite and silica, and uses an anionic surfactant to provide superior thixotropy. , long-term stability has been improved and a major objective has been achieved.

The configuration of the present invention will be described below.

The organically modified montmorillonite used in the present invention is a substance in which a quaternary ammonium salt type cation activator or a nonionic higher organic polar compound is chemically bonded to montmorillonite, which is a clay mineral, and is a commercially available product. For example, Benton (Benton 27 manufactured by National Red Co., Ltd.)
Bentone 34, Bentone 38, etc.), and any of them can be used. These can be arbitrarily selected as required, and one or more types can be blended. The preferred amount of these components is 0.2 to 3.0% by weight, more preferably 0.8 to 2.0% by weight. 0.2% by weight
If it is less than 3.0% by weight, good thixotropic properties cannot be obtained, and if it exceeds 3.0% by weight, the gloss and retention over time (peeling) of the nail polish coating will deteriorate.

The silica used in the present invention may be well-known, for example,
A commercially available product is Aerosil TT200. Aerosil #3
00, Aerosil ■380, or Aerosil R972. Among these, those having a particle size of less than 0.01 μm, such as Aerosil 200, Aerosil #300, and Aerosil Jlzt$380, are preferred from the viewpoint of thixotropy.

The preferred amount of these components is 0.1 to 2.0% by weight, more preferably 0.5 to 1.5% by weight.

If it is less than 0.1% by weight, good thixotropy will not be obtained and stability over time will deteriorate. If it exceeds 2.0% by weight, the gloss of the enamel coating will be poor in terms of usability, and the durability over time (peeling) will also be poor.

The anionic surfactants used in the present invention may be well-known ones, such as dioctylsulfosuccinate sodium, dioctylsulfosuccinate calcium, dioctylsulfosuccinate barium, di-2-ethylhexylsulfosuccinate sodium, di-n-hexylsulfosuccinate sodium. N-acyl sarcosine salts such as maruhokoha) heptaic acid salts, sodium lauroyl sarcosine, calcium lauroyl sarcosine, sodium valmitoyl sarcosine,
Sodium lauryl sulfate, lauryl? ii! Calcium ilate, sodium myristyl sulfate, alkyl sulfate ester salts such as sodium cetyl sulfate, polyoxyethylene (hereinafter abbreviated as POE) sodium lauryl ether sulfate, POE lauryl ether sulfate triethanolamine, POf': nonylphenylsulfate Examples include POE alkyl ether sulfate salts such as triethanolamine.

The blending amount is preferably 0.01 to 1.5% by weight, more preferably 0.1 to 1.0% by weight. If it is less than 0.01% by weight, long-term stability is insufficient, and 1.5% by weight.
If it exceeds this, the stickiness (peeling) tends to worsen over time.

The non-aromatic solvent used in the present invention broadly refers to organic solvents other than aromatic hydrocarbons such as toluene and xylene, such as n-butyl acetate, isobutyl acetate, ethyl acetate,
Examples include methyl ethyl ketone, acetone, n-butanol, isopropyl alcohol, and ethyl alcohol. One or more of these solvents can be blended. The preferred amount of these components is 60 to 85% by weight.

Furthermore, in addition to the above-mentioned essential ingredients, the nail beauty preparation of the present invention contains film-forming agents, resins, plasticizers, pigments, pearlescent agents, etc. that are usually used in nail beauty preparations, and also contains ultraviolet absorbers, humectants, Drugs, fragrances, moisture, etc. can also be added as appropriate. Of course, these must be used under qualitative and quantitative conditions that do not impair the purpose of the present invention.

[Effect of the Invention 1] The present invention relates to a nail beauty product that is safe for the human body, has no precipitation of pigments or pearlescent agents, has excellent stability over time, and has good coating film properties and usability. Compared to conventional technology that uses aromatic hydrocarbon solvents such as toluene and xylene, it is highly safe for the human body, causes very little damage or pain to nails, and is also superior in terms of retention over time (peeling). ing. Also, compared to nail polishes that do not contain aromatic hydrocarbon solvents such as toluene and xylene, the pearl agent's sinking properties, stability over time,
It has even better quality in terms of coating film properties and usability.
